DEMOUNTABLE RIM.

Specification of Letters Patent.

Patented Sept. 12, 1916,`

Application led December 9, 1915. Serial No. 65,931.

To all 1li/tom it may concern:

Be it known that l, Ur'roN S. LANDERS, a citizen ofthe United States, residing at Bakersfield, in the county of Kern and State of California, have invented certain new and useful Improvements in Demountable Rims, of which the following is a specification.

T his invention relates to automobile tires, and pertains especially to the class of den'iountable'rims for connecting inflatable tires with wheel rims.

The object ot the invention is to provide, in a delnountable rim, certain novel improvements in this particular' class ot rims, and to furnish a specially constructed two part interlocking rim of simple and expeditious adaptability.

A further object of the invention is to provide novel and peculiar locking niembers in a two part demountahle rim, and to furnish means cooperating with the locking members for retaining them in locked position.

Various other objects, advantages and improved results are attainable in the practical application ot' the invention as will be 'found in the specification and claims following.

In the. accompanying drawings forming part ot' thisI application: Figure l isa side elevation ot part oli a wheel showing the application ot' the invention. Fig. 2 is an enlargedrross sectional view taken on the dotted line Fig. l, and through onel ot' the interlocking rim portions, with the tire removed. Fig. il is a detail perspective view showing an interlocking portion ot the demountable rim unlocked. llig. l is aninverted plan view'ot the. interlocking' pori tions with the key partly inserted. Fig. 5 is an inverted perspective view ot one ot thelocking wings. Fig. 6 is a sectional perspective View of a modification.

The same reference'characters denote. the Same parts throughout the several views ot l am well aware that deinountable rims having interlocking members, ot various construction have been '(levisecl, and that various-devices have been provided for keying or securing said members together, but my invention provides specially constructed locking members cooperating with special` keys, alfording a closer union of the members, and producing a continuous evenA smooth .surface for the tire.

My invention further Yembodies simple and inexpensive construction and affords l means Jfor expeditious manipulation of the parts in producing a more durable, compact and efficient demountable rim.

With these purposes and objects in View,

the invention will now be described'n de rim l, and having a supporting shoulder 8,'

opposite the shoulder 3, for the 'other member 9, ot' the demountable rim. The said annular flange 7, projects inwardly between the rim l and the demountable rim member 9, so as to leave a space between the rim 1 and the members 4 and 9, for the purpose as will be hereinafter explained. The members 4 and 9 have flanges 4 and 9 respeetively tor the tire l llaeh of the demountable rim members 4 and 9 have their meeting edges provided, at intervals throughout their circumference, with meshing portions et special construction so that said portions overlap flush with the inner-:and the outer laces 'of the mem` bier-s.` ln perfecting the meshing elements l `term a plurality ot' V-shaped cut outs 1 0 inthe meet-ing edges of the members 4 and 9,

and these eut outs are separated by V-shaped" wings 1l, which lit the, cut outs so that the wings and eut-outs ot one rim member mesh with the wings and cut-outs of the other rim member' crosswise ot the rim. The end or point of each of the wingsll 'is provided with a head l2 having an undercut edge 13 extending across thevend of the vunder tace of each wing.

The undercut edges lll are tapered lengthwise so as to receive a wedge shaped locking key 14 having beveled edges fitting the undercut edges 13, and ythereby locking the demountable rim members' l and 9 firmly and' securely together. rl`he heads 1Q are preferably of a i thickness equal to the space, hereinbeore referred to, between the deinountable rim and the fixed rim l, so that the heads with the keys will rest centrally upon the fixed rim l, whereb)v the demountable rim is supported centrallyv aswell as at the edges by the flange shoulders 3 and S.

Referring to the modification shown in Fig. G. the lixed rim l5, has ananlnilar enlargement or chair 1G, forming a rest support for either the preferred form or for the moditied `form ot' demountable rim 1T. The clamping side 1S has an annular flange lf) extending inwardly between the fixed rim and the rim 1T, and forms a rest or support for this rim. The demountable rim 1T has a side llange Q0 integral therewith, and an inner edge provided with alternate V-shaped notches 2l separated by a V-shaped wing- 2L). The side flange 23 of the rim member 1T, has V-shaped wings 24 which lit the notches :21. and V-shaped openings 21 for the wings The wings have undercut heads Q5 for a tapered beveled edge key QG.

lt will be understood that the locking features ot the demountahle rims in either form are only necessary at certain intervals in the circumference ot' the rim, preferabl)v at three places in the rim equally spaced apart which will produce the desired results. Obviously either -form ot' demountable rim ma f be used on either form ot' fixed rim as desired or as occasioninay demand, but for heary rehiclcs or trucks the modified form of fixed rim is preferalile as it affords a more substantial base or rest for the demountable rim.

l do not wish to be understood as limiting the invention to any particular size or material, nor to the number of interlocking members in the deniountable rim, nor to the application of the demountable rim, but reserre the right to make such changes and alterations therein as may be found expedient in the manufacture and practical application of the invention as may come within the scope of the appended claims,

llaving thus described my invention what l claim as new and desire to secure by Letters latent is l. A demountable tire-carrying rim comf prising a pair olf annular members having tooth-like meshing sections Composed of V-shaped wings and V-shaped cut-outs, an enlarged head at the end of each wing and having a tapering undercut, said undercuts forming a l e y\\-a v across the wings, and tapering locking keys l'or securing the members together.

A denimnxitable tire-carr vin-g rim comprising a pair o'l' annular members,- the contacting edge of each member having a plurality o'l alternating wedge shaped wings and cutouts assembled at intervals through the circumference ol' the rim, the. wings )vedging into the cut-outs erosswise ot the rim, an enlargedl head upon each wing and having an undercut inner edge, and a bev- A eled key extending through the undereuts for locking the members together.

A demountable rim comprising two members each of which has sections thereof composed of V-shaped wings projecting in opposite directions from the adjacent edges ot' the members, the wings oi one member meshing with the wings oi the otheruneniber across the central circumference oiE the rim, an enlarged head on the outer end of each wing, said heads each having an undercut beveled 4t'ace tapering lengthwise, one set of heads being separated by the wings of the other set, and a beveled edge tapering key fitting the undercuts and extending across the wings l'or locking the members together.

In witness whcreotl hereunto set my hand in the presence of two witnesses.
